By the combination of heat treatment in flowing (99.8% N[sub 2] + O.2% O[sub 2]) gas and in flowing H[sub 2] gas, the authors have succeeded in synthesizing Bi[sub 2]Sr[sub 2]CaCu[sub 2]O[sub y] having the stoichiometric cation composition with the highest T[sub c] of 96 K among the Bi2212 related compounds prepared so far. The oxygen content y was measured to be 9.72 by the method of coulometric titration. Alternating current magnetic susceptibility measurements for powdered samples revealed that the superconducting transition of this Bi2212 phase is rather sharp and the Meissner volume fraction is comparable with YBa[sub 2]Cu[sub 3]O[sub 7].
